AUTOMATIC KEYBOARD FOR-TEACHlNG TYPE-WRITING,

SPECIFIGATION forming part of Letters Patent No. 694,944, dated March 11, 1902,

Application died September 20, 1901. Serial lie. 76,008, (No model.)

To aZZ whom it may concern:

Be it known that I, Josnrn Onnmmsnma subject of the King of Great Britain and Ireland, residing at 128 lVest Bromwich road, Walsall, in the county of Staiford, England, have invented new and useful Improvements in Automatic Keyboards for Teaching TypelVriting, (in respect whereof I have applied for a patent in Great Britain, to bear date March 20, 1901, No. 5,858,) of which the fol lowing is a specification.

This invention relates to keyboards for use in acquiring the art of manipulating or working type-writers without the employment of the actual machine for that purpose, the objects being to provide a keyboard whereof the keys act independently of one another, their operation being approximately similar to the keys of a type-writer proper and to effect economy in the cost of construction.

In the accompanying drawings, Figure 1 is a side view of a type-writer practicekeyboard constructed according to my invention, a portion of the end of the body portion being removed to clearly show the internal arrangement. Fig. is a plan of one-half of the keyboard. Fig. 3 is a view of the inner side of the keyboard.

In carrying out my invention I arrange the keys A A upon a carrier or support B, which may be constructed of wood or cardboard or partly of wood and partly of cardboard in such a manner to represent the keyboard of any desired type-writing machine. The keys are similarin appearance to those of an ordinary typewriter and may be formed of wood, celluloid, metal, bone, or any oth 1' suitable material. Each key is attached to a stem a, which works in an aperture formed in the board or gallery Z) oi the carrier, the lower extremity of the stem being formed with an eye a. Through the eyes pertaining to each row of keys is threaded a piece of elastic, or a continuous length of elastic 0 may be threaded backward and forward through the adjoining rows of eyes, as shown clearly in Fig. 3, the elastic being retained in position by threading the same through the eyes of small staples d, secured in the board or gallery Z) near the eyes a pertaining to the stems a. The spacing bar or key A is supported by two eyed stems a a, the elastic c being secured either by binding, as shown at 0 or in any other convenient manner.

By means of the construction above described each keyA maybe depressed without interfering with the adjacent keys, the clastic effecting the return of the key to its normal position upon the removal of the pressure therefrom.

The arrangement I have described and illustrated for allording elastic movement to each key, whereby its rebound is secured after depression, is not only inexpensive in character, but is very eliective in operation.

It will be apparent that the invention is capable of employment for practice in connection with any description of type-writer, although the drawings illustrate the keys as arranged upon a machine of the Yost pattern.

What I claim as my invention, and desire to secure by Letters Patent, is

In apparatus for use in acquiring the art of manipulating or working a type-writer, a carrier or gallery formed with apertures, separately mounted keys provided with eyed stems working in said apertures, elastic threaded through the said eyes and staples, secured to the inner side of the gallery, for holding the elastic in position, substantially as herein described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JOSEPH CHALLINGER.
